Details of outcome We received 14 responses from energy suppliers, consumers groups, charities and delivery bodies. Many responses broadly supported our proposals. Several organisations also provided their views on making the ban on acquisition-only tariffs permanent in the future. We have carefully considered the feedback received and potential impacts to the energy market. Based on this, we are going to extend the existing ban on acquisition-only tariffs and the associated market-wide derogation until 31 March 2027. The market-wide derogation allows suppliers to offer specific deals for their existing customers. These are not made available to new customers.
